Material transparent to UV but reflective to visible light?

[Ariellev]

Hi all,
I am in a search for a material that is transparent in UV wavelengths, but reflect light in the visible wavelength (e.g. the opposite of standard glass). does anyone here know of such a material?

Thank's in advance

Some metals can do this, if the plasma frequency is right.

I think Teflon/PTFE transmits UV light.
